Application filed December 21, 1914. Serial n. 878,41

To all whom it may concern:

Be it known that I, AIKEN G. TAYLO a citizen of the United, States,residing at Richmond, in the county of Henrico, State ofv Virginia, haveinvented certain new, and, useful Improvements in Windows; and I dohereby declare the followingto be a full, clear, and exact descriptionof the invention, such as willenable others skilled inthe art to whichit appertains to makeand use the same.

This invention relates to windowsv of that class wherein a sashisadapted to be swung to a tilted position or vice versa, for the purposeof regulating ventilation, to allow the glass pane of the window to becleaned with safety and facility, and for other purposes, and is in thenature of an improvement upon the window forming the subject matter ofPatent No. 1,117,954, granted to Dorsett A, Davison, November 17, 1914.

While my invention in its broad aspects is basedupon the same generalprinciples as the structure of this Davison patent, yet 1t difierstherefrom in certain material respects and possesses certain manifestadvantages thereover. For instance, instead of employing a substantiallyflat follower plate, a portion at least of which is vlsible atv alltimes, whether the window be open or closed, I make use of aspool-shaped follower, that is one having a pair of disk-like spacedflanges connected by a central barrel section, and this follower is solocated within and slides over a guide strip of such peculiarconstruction that it is entirely concealed withinthe strip when thewindow is closed. this follower is so constructed as to have a cam-likebinding action against the guide strip of the windowframe when the sashis tilted, thereby assisting in hold ing the sash stationary in anyposition to which it may be tilted. Furthermore, in-

stead of employing a substantially flat pivot plate to which the windowsash is pivoted, as is done in the Davison structure, I provide the sashstrip connected to the window sash with a cam-like pivot stud rigidtherewith, this stud having a cam-like binding action against theadjacent flanges of. the guide strip of the window frame when, the

sash is tilted, so that the sash will be held ushi ted, pen p i on smayb d ired.

Another. feature of advantage incident tomy invention over the Davisonconstruction, 1s that, when the window sash. embodying my nventioniscompletely closed, that is to say 1s in its vertical position in theframe, a weather-tight joint is formed. between both the longitudinaledges of the sash strip and both the longitudinal edges of the guidestrip carried by the windowfframe, while in the Davison structure such,weather-tight j ointis formed between but one of the longitudinal edgesof; the sash strip, and one of the ad acent longitudinaledges of theguide.

strip at. thewindow frame.

Furthermore, in the present instance, when the sash is in its closed orvertical position, it is held locked or latched in such position bymeans of a pin, which when it is desired to open the window, isdepressed or moved out of locking position by contact with a short camor tripping strip carried by the guide strip at the window frame, thewindow sash being movedvertically a short distance to bring-the pin intocontact with the cam or tripping strip.

My invention consists in the construction, combination and arrangementof parts set forth in and falling within the scope of theappendedclaims. v

"In the accompanying drawings: Figure l is a perspective view of awindow embodying my invention, the lower sash being shown as swunginward to a horizontal position. Fig. 2 is a detail perspective view ofone side of a sash and showing the sash strip, the follower plate andthe rigid pivot stud. Fig. 3 is a cross sectional view taken through oneside ofthe sash and thewindow frame, showing the sash in its vertical orpin holding the window when it has been slightly moved vertically. Fig.-5-is-aperspective view of the bottom portion offone of the side bars ofthe sash and a portion of one of the guide strips of the window frameandshowing the position of the sash strip relative to. the guide strip whenthe window' isc ompletely. open or in horizontalposition. Fig. 6 is adetail view of the lower portion of one of the sidebars of the sash andillustrating a portion of the sash strip and the follower in elevationand the rigid pivot stud'in cross section. Fig. 7 is a detail view of aportion of one of the guide strips and showing the cam strip elementformed thereon.

In the present instance in F ig. 1, I have shown merely by way ofillustration, a con ventional form of window frame with the upper windowsash closed and the lower sash tilted inward to open position. I willdescribe the invention as applied to the lower sash, but it will, ofcourse, be understood that it is applicable to the upper sash as well.

Referring now to the accompanying drawings in detail, the letter Aindicates the window frame as an entirety, and B indicates the upper andlower window sashes. Contining the description particularly to one sash,for instance the lower sash B, I provide at each side of the windowframe a longitudinally extending metallic guide strip which is indicatedas an entirety by the letter G. This strip is preferably constructed ofa single piece of metal which is bent longitudinally to form the flatrear wall 1 through which nails or screws are passed to fasten the stripto the window frame. From this rear wall I project the side walls 2 and3 of the strip. The side wall 2 includes the inwardly and longitudinallyextending double or two-fold flange 4 and the inwardly extendinglongitudinal flange 5 which extends parallel with the flange 4, the wall6 connecting these two flanges. Likewise the side wall 8 of the strip isbent and folded to form the longitudinally and inwardly extending doubleflange 7 alining with and extending oppo site to the double flange 4,the material at the free longitudinal edge portion of this wall 3 beingthen bent outward to form the flange 8. The flange 7 of the wall 3 is aguide strip G equipped with a curved cam or tripping strip 9 as shown inFig. 7 for. the purpose hereinafter mentioned. It is to be noted thatthe longitudinal sections of the double flanges 4 and 7 are spaced apartand, being of sheet metal, possess a certain resiliency so that when theadjacent sides of the window sash bear against these flanges they willbe first pressed inward and then sprung outward to form a weather tightjoint with the sash strip, and this joint will be maintainedirrespective of the contraction or expansion of the wood of either thewindow frame or sash.

The window sash B is provided with the usual side bars 6, each of whichis longitudinally rabbeted at one side edge as at 10. To the outer faceof each side bar I fasten a longitudinally extending flat metallic inconjunction with the body of the strip.

The flange 14 at its lower end terminates short of the lower end of thestrip, this forming a shoulder 16 for the purpose here inafter setforth.

Rigid with and projecting inward from the lower end of each sash strip11 is apivot stud including the shank section 17 and the heads 18. Theshank 17 of the stud is approximately elliptical in cross section withthe longer axis of the ellipse running vertically when the window sashis in its vertical closed position. This pivot stud is adapted toproject through the slot 4 formed by the confronting longitudinal edgesof the flanges 4 and 7 when the parts are assembled, the shank 17 of thepivot bearing against these confronting edges while the heads 18 bearagainst the sides of the flanges 4 and 7. It is to be noted that bymeans of these pivot studs 79 the window sash is pivotally connectedwith the guide strips at the sides of the window frame, and when thesash is moved to its vertical position, the longer axis of the studswill also extend vertically so that the pivot studs themselves will notprevent the free sliding of the sash strips and consequently the sashalong the guide strips. /Vhen, however, the window is tilted inward orinclined as in opening the same for ventilation, as is shown in Fig. 1,the longer axes of the shanks of the studs are turned crosswise of theguide strips and consequently the shanks 17 of the studs will tend tobind against the confronting longitudinal edges of the double flangesand 7 of the guide strip and thus the window may be held in any positionto which it is tilted without the use of any additional latching means.

Pivotally connected as at 19, adjacent to the lower end portion of eachsash strip 11, and above the pivot stud thereof, is a link 20, the freeend of which carries a follower element 21. In the present instance thisfollower is made fast with the free end of its link, and is ofspool-like form, that is L to say is formed with the disk-like endflanges 22, connected by the barrel 23, which is also approximatelyelliptical in cross section. Each'follower 21 is adapted to slide on thedouble flanges 4 and 7 of the adjacent guide strip G, and to be guidedthereby, one end flange 22 of the follower bearing against the innerfaces of these flanges 4 and 7, while the flat end flange 22 of thefollower bears against the outer faces Ill 1 of theseflanges-4 and '7,the 'barreltsection- 23 of each follower sliding between the confronting longitudinal edges of such flanges of the guide strip.

Socketed in each side bar of the window as shown inFigs. 2 and 4,isalocking sash, pin24, the an opening spring 26 normally forcing thepin outward head of which extends through into locking position. Thispin is located abovethe point where the link 20 of the fol lower ispivoted to the sash strip. Now, when the window sash is swung to itsclosed or vertical position, the beveled. end 27 of the head of the pinwill strike against the free longitudinal edge of theflange 8 of theguide strip and be momentarily pressed inward, but as soon as the windowsash is completely closed with the sash bars in parallelism with theguide'stripsof the window frame, and with the flange 14 of the sashstrip receiving and engaging the flange 8 of the guide strip G, andwiththe free longitudinal edge of the flange 5 of the guide stripseating in the groove 13 of the sash strip, this'pin will spring outbehind the flange 8 and interlocking therewith will hold the window inlatched position against ordinary shocks and jars and prevent it fromaccidentally swinging inward; When, however, it is desired to tilt thewindow to open the same, the closed window is first shifted verticallyuntil the head of the locking pin 24 strikes and rides up over the camstrip 9 of the guide strip G, and this will cause the locking pin to bedepressed inward against the tension of the spring and permit the windowto be opened or tilted inward, as the top surface of this cam strip 9'the flange 8.

One end of each sash cordc is attached at 28 to a link 29 connected withthe adjacent follower element 21, the sash cordrunning over the pulleysin the frame to the weights in the usual manner. I

In connection with the followers I wish to call particular attention tothe fact that the barrel section 23 of each follower is alsosubstantially elliptical in cross section, with the longer axis of thebarrel extending vertically when the window sash is closed or in itsvertical position, so that when the window is tilted or forced partiallyinward, the

outward pull of the link 20 upon its fol-- lower will tend to cause thelatterto be pulled sidewise and also act to bind against the doubleflanges 4 and 7 and assist in holding the window in tilted position.

From the above description, taken in connection with the accompanyingdrawings,

the construction and manner of employing my invention will be readilyapparent to thoseskilled in the art. For each window sash two guidestrips G are employed, one

25 in the strip 11, a suitable at'each: sideiof: thevwi-ndowaframeaLikewise, of course, each window sash iscrjuippede: with two sashstrips,-.each=nsash' strip carry-i ing-1a follo'werandra pivot stud,Asbefore mentioned the pivot :studs of theasash= strips' are insertedinto the-longitudinalspace or slot between. the double Or two-foldflanges-1 4v and 7, and when thewindow sash is in its vertical position,the longitudinal flange5 of the guide strip Gr' fits into thelongitudinal groove 13 formed by the plate. 11 and the rabbeted'edgeofthe sash bar, formingwa: weather-tight joint at this sideeof thewindow; Likewise the. flange 8" of the guide strip G of the window frameinterlockswith the longitudinal flange 14 of thesashstrip,

fitting into the groove 15 formed by this: 1

flange so that a weather-tight. joint is;

and the flange 14 of the sash. Also-inthe' vertical or closed positionof the window sash the locking pin will interlock with the flange andhold the window against acci dentally opening or tilting, asheretoforedescribed. Now, if it is desired to open and tilt the-window,the sash is first shifted up ward. vertically until each lockingpinstrikes-the adjacent cam strip 9, when such locking pin willbedepressedandthe win.- dow may be tiltedto open position. With. thetilting ofthe window, the pivot studszp are turned relative. to theadjacent'orlongitudinal edges of the double or two-fold flanges 4 and 7and the shanks of thesestuds beingellipticalin cross section will. thusbind with considerable friction against the edges of these doubleflanges so that. the window may bemaintained inany position'to which itis tilted without employing. any additional locking or holdingmeans.

exceedingly'simple, yet efficient'form of window of this class, and onewherein. a weather tight joint is formed between both the inner andouter faces of the sashbars. and the inner and outer faces of the guidestrip. It will also be seen that when the window is swung to itshorizontal position, or at an angle ofninety degresrelative to thewindow frame, the shoulder 16 at the lower end of the flange 14 of thesash strip will strike against the adjacent portion, of the flange ofthe guide strip Grand prevent the window dropping or opening anyfarther.

Furthermore, it will be noted that both the follower elements and thepivot studs will lie and move within the confines of the sides of theguide strips at the window frame when the parts are assembled, and thatthe resiliency of the double fold flanges 4 and 7 insures that therewill alwaysbe maintained a weather-tight, snug joint between the sashstrips and the guidestrips when the window is closed.

It will be noted that I have provided an While I have herein shown anddescribed one particular embodiment of my invention, I wish it to beunderstood that I do not confine myself to all the precise details ofconstruction herein set forth by way of illustration, as modificationand variation may be made without departing from the spirit of theinvention or exceeding the scope of the appended claims.
